-
A. None of these
-
B. Work
-
C. Energy
-
D. Force
Explanation

So, change in momentum in one second is defined as force.
-
A. Law of Universal Gravitation
-
B. Newton’s First Law
-
C. Newton’s Third Law
-
D. Newton’s Second Law
Explanation
The formula for Newton's Second Law of Motion is:
F=ma
Where:
-
F = Force (in Newtons, N)
-
= Mass of the object (in kilograms, kg)
-
= Acceleration of the object (in meters per second squared, m/s²)
